Abstract
Catechol-type siderophores secreted by a strain of soil bacteria in three different medium were assayed by two high-resolution TLC.The results showed different medium had a significant effect on the secretion of catechol-type siderophores,and in three different medium strain S1 produced different catechol-type siderophores.The effect of Al~(3+) on Catechol-type siderophores by S1 were also assayed.The results showed Al~(3+)had a significant stimulation on the secretion of catechol-type siderophores.Moreover,Al~(3+)could to some extent counteract the repression of Fe~(2+)on siderophores production.In KMB medium four catechol-type siderophores were identified and all ones except for 2,3-dihydroxybenzoic acid(2,3-DHBA) had high affinity for Al~(3+).
